c# - Partial scaling of a composed elements in WPF -

I am in the following situation: Designing an interactive flow-chart GUI I animate the scale below the flow-chart animation Was stuck with. Elements that compose the flow-chart are reduced, but they remain active.

I have something like this:

  & lt; Canvas canvas.lift = "55" canvas .Top = "720" height = "100" width = "500" tag = "stepdown" & gt; & Lt; Line stroke = "# 99ccff" strokectaction = "8" x1 = "0" x2 = "720" Y1 = "10" Y2 = "10" & gt; & Lt; Polygon Stroke = "Black" StrokeThickness = "2" Points = "0,30 40,0 40,60" canvas Lift = "- 20" canvas. Tap = "-20" Fill = "# 99ccf" & gt; & Lt; / Polygon & gt; & Lt; Polygon stroke = "black" strokectniness = "2" points = "0,0 0,60 40,30" canvas Lift = "720" canvas. Tap = "-20" Fill = "# 99ccf" & gt; ; / Polygon & gt; & Lt; Image canvas. Late = "- 50" canvas Tap = "- 70" height = "53" name = "image32" source = "img / outlet.png" section = "fill" width = "30" tag = "relative" /> & Lt; / Canvas & gt;   
 And I would like to move the whole canvas and its elements to the left - there is no problem with  translation transforms . In addition, I do not want to reduce the problem with  line  only with  scale transform .  
 But at the same time (!), I want to stick the  polygon  to end two lines of line when the line is scaled, then  polygon , at least one, floats.  
 I do not know how to adopt these elements or to define them on a relative basis. It works fine with scale on the entire  canvas , but it also changes  polygon  and  images .   
 
 
 You have to define qualities for me, as attachment attributes even such behavior Define who track these points according to polling placements. Then you can tie these properties to the start / end points of the line. In this way the line should be dominated by polygons. But I did not try it, it's just a design idea.
